A PLA is similar to a ROM in concept except that ____________a. It hasn’t capability to read or write operationb.It doesn’t provide full decoding to the variablesc. It hasn’t capability to read only

The statement is incomplete, but I can provide information based on the options given:

a. A PLA (Programmable Logic Array) is similar to a ROM (Read-Only Memory) in concept except that it doesn't have the capability to perform read or write operations. This is incorrect. Both PLAs and ROMs can perform read operations. The main difference is that data can be written to a PLA, while a ROM is pre-programmed with data that cannot be changed.

b. It doesn’t provide full decoding to the variables. This is correct. Unlike ROMs, PLAs do not provide full decoding of variables. In a ROM, each possible input will correspond to a unique output. In a PLA, this is not the case. The output depends on the logic implemented in the PLA.

c. It hasn’t capability to read only. This is incorrect. Both PLAs and ROMs can perform read operations. The main difference is that data can be written to a PLA, while a ROM is pre-programmed with data that cannot be changed.
